If a creditor, within sixty days after having transmitted to an obligor a statement of the obligor’s account in connection with an extension of consumer credit, receives at the address disclosed under section 1637(b)(10) of this title a written notice (other than notice on a payment stub or other payment medium supplied by the creditor if the creditor so stipulates with the disclosure required under section 1637(a)(7) of this title) from the obligor in which the obligor—

(1) sets forth or otherwise enables the creditor to identify the name and account number (if any) of the obligor,

(2) indicates the obligor’s belief that the statement contains a billing error and the amount of such billing error, and

(3) sets forth the reasons for the obligor’s belief (to the extent applicable) that the statement contains a billing error,

For the purpose of this section, a “billing error” consists of any of the following:

(1) A reflection on a statement of an extension of credit which was not made to the obligor or, if made, was not in the amount reflected on such statement.

(2) A reflection on a statement of an extension of credit for which the obligor requests additional clarification including documentary evidence thereof.

(3) A reflection on a statement of goods or services not accepted by the obligor or his designee or not delivered to the obligor or his designee in accordance with the agreement made at the time of a transaction.

(4) The creditor’s failure to reflect properly on a statement a payment made by the obligor or a credit issued to the obligor.

(5) A computation error or similar error of an accounting nature of the creditor on a statement.

(6) Failure to transmit the statement required under section 1637(b) of this title to the last address of the obligor which has been disclosed to the creditor, unless that address was furnished less than twenty days before the end of the billing cycle for which the statement is required.

(7) Any other error described in regulations of the Bureau.

For the purposes of this section, “action to collect the amount, or any part thereof, indicated by an obligor under paragraph (2)” does not include the sending of statements of account, which may include finance charges on amounts in dispute, to the obligor following written notice from the obligor as specified under subsection (a), if—

(1) the obligor’s account is not restricted or closed because of the failure of the obligor to pay the amount indicated under paragraph (2) of subsection (a), and

(2) the creditor indicates the payment of such amount is not required pending the creditor’s compliance with this section.

Pursuant to regulations of the Bureau, a creditor operating an open end consumer credit plan may not, prior to the sending of the written explanation or clarification required under paragraph (B)(ii), restrict or close an account with respect to which the obligor has indicated pursuant to subsection (a) that he believes such account to contain a billing error solely because of the obligor’s failure to pay the amount indicated to be in error. Nothing in this subsection shall be deemed to prohibit a creditor from applying against the credit limit on the obligor’s account the amount indicated to be in error.

Any creditor who fails to comply with the requirements of this section or section 1666a of this title forfeits any right to collect from the obligor the amount indicated by the obligor under paragraph (2) of subsection (a) of this section, and any finance charges thereon, except that the amount required to be forfeited under this subsection may not exceed $50.
